The direct drives of NORD drivesystems brought more than just higher reliability and reduced financial and labour expenditure for maintenance activities. The relative investment costs for purchasing new gear units also proved to be lower.Gravel plant cuts costs and reduces maintenance expenditures by using geared motors. In many gravel pits, stone crushing plants and similar operations, motive power for conveyor belts is provided by shaft and belt drives. Until recently, this was the situation at the gravel plant of NorStone AS in Tau, located in the southwest region of Norway. Recently NorStone, a subsidiary of HeidelbergCement AG, decided to change to robust geared motors. This option promised lower investment costs and increased operational reliability, along with better process security. Reduced energy consumption thanks to higher efficiency was also anticipated.NorStone is Norway’s largest producer of gravel products. The company supplies aggregates for concrete and asphalt, pipe cover gravel for coastal regions, and other special products. Each year NorStone’s production facilities produce over 6.6 million tonnes of gravel products in various sorts and quality classes. The demand is large, and even with its present annual production capacity of 2.3 million tonnes of material the Tau plant can scarcely meet the demand. This makes it especially important to ensure that the plant is operational as much as possible and to minimise unplanned downtime.Familiar advantages plus increased reliability with direct drivesGeared motors are actually not new in gravel pits. Direct drives of this sort were commonly used in the 1980s, but in subsequent years many plants changed to belt drives because spare parts for these drives were always quickly available, while manufacturers and suppliers of geared motors were unable to offer stocks of spare parts with the same good availability. "We have found that service and spare parts for geared motors are now available to us very quickly. We hold some parts in stock ourselves, and for all of the rest we have complete trust in NORD Drivesystems as a supplier", explained Ivar Ullestad, Maintenance Manager at Tau, as the reason for going back to the former solution. "This allows the known advantages of drive solutions with geared motors to be fully exploited. In particular, direct drive leads to higher reliability, which means less downtime and therefore less lost production time. Another important aspect is that less maintenance is necessary. In addition to reducing maintenance costs, this increases safety in the plant", added Ullestad.Measurably less wear than with shafts and beltsWorking conditions are a significant factor in such considerations. "You have to bear in mind that we work outdoors all year round. Most of the locations for the conveyor belt drives are open and unprotected. Due to the harsh weather conditions in the west of Norway, with wind, rain and sleet, as well as the dusty and rather unpleasant environment at the site, we try to minimise repair and maintenance times for our maintenance staff." The Tau plant runs seven days a week, 24 hours a day in shift operation. The 168 production hours include 16 hours of scheduled maintenance. The plant is only shut down for the winter break. During this break, annual maintenance inspection and overhaul tasks are performed in two to three weeks. The direct drives have contributed to a distinct increase in reliability, amounting to approximately 4.5 per cent, in the last three years. "We are very satisfied with this trend. With the change from shaft and belt drives to direct drive with geared motors from NORD Drivesystems, in the first place we eliminate the aspect of belt wear, which is considerable. Furthermore, no water or dust can enter the drive mechanism. This means that the decision in favour of compact, robust geared motor units yields clear advantages and has therefore proven to be an intelligent move", summarised Per Thu, Production Manager of the NorStone plant. The direct drives brought more than just higher reliability and reduced financial and labour expenditure for maintenance activities. The relative investment costs for purchasing new gear units also proved to be lower. Replacing a complete package, consisting of a shaft-type gear unit along with belt pulleys, belts, a shed, belt cover and motor, turned out to be more costly than purchasing a comparable geared motor. As a series of periodic gear unit replacements was anyhow in the works, a comprehensive switch from shaft and belt drive to direct drive was a logical choice for Ullestad. He is currently working to standardise drive components. "With a staged cutback in drive systems for the conveyor belts, we are standardising aspects such as motor size, shaft size and drum diameter in order to limit diversity and thereby simplify maintenance, stock management and service. We are also developing backup solutions, which among other things involves keeping components in stock ourselves," according to the maintenance manager.NORD Drivesystems Pvt.

World Environment Day spotlight on innovation and circularity

On World Environment Day, the Indian cement industry reiterated its commitment to supporting India’s climate ambitions through sustainable manufacturing, resource efficiency and the adoption of cleaner technologies.

The Cement Manufacturers’ Association (CMA) said the sector remains aligned with the Government of India’s Net Zero commitments and is accelerating efforts to reduce its environmental footprint while supporting the country’s infrastructure and development agenda.

Parth Jindal, President, CMA and Managing Director, JSW Cement, said the industry is increasingly adopting cleaner technologies, improving energy efficiency and expanding the use of alternative fuels and raw materials. He also highlighted the growing importance of circular economy practices, where industrial by-products and waste streams from one sector are utilised as resources in another.

“The Indian Cement Industry is aligned to the Government’s commitments on carbon mitigation and is accelerating the adoption of cleaner technologies, resource efficiency and circular economy practices while actively exploring the potential of Carbon Capture, Utilisation and Storage (CCUS) as a critical pathway for deep decarbonisation,” said Jindal.

He added that coprocessing industrial waste and by-products helps conserve natural resources, reduce disposal requirements and lower the environmental footprint across multiple sectors.

According to Jindal, sustainability is no longer limited to manufacturing processes but is increasingly influencing investment decisions, innovation strategies and long-term growth plans within the industry.

Echoing similar views, Dr Raghavpat Singhania, Vice President, CMA and Managing Director, JK Cement, said sustainable development extends beyond emissions reduction and must also focus on responsible resource utilisation and waste minimisation.

“Sustainability in the built environment cannot be measured by emissions alone. It is equally about how efficiently we use resources, how effectively we minimise waste and how responsibly we create the infrastructure that will serve future generations,” said Singhania.

He noted that the cement industry is advancing its sustainability agenda through greater resource efficiency, increased circularity, technological innovation and continuous improvements in manufacturing practices. As a key contributor to India’s infrastructure development, the sector has a critical role to play in balancing economic growth with environmental responsibility.

On the occasion of World Environment Day, industry leaders reaffirmed their commitment to supporting India’s climate goals while delivering the materials required for resilient, durable and sustainable infrastructure.

Environmental sustainability requires immediate action, not just long-term commitments and discussions. Recycling, circular economy practices, and technology-driven waste management can help industries reduce environmental impact while supporting sustainable growth.

Author: Jignesh Kundaria, Director and CEO, Fornnax Technology

World Environment Day serves as an important reminder that environmental sustainability can no longer remain confined to discussions, reports, or long-term commitments. The environmental challenges facing the world today demand immediate, measurable, and collective action. Across industries and communities, waste generation continues to outpace our ability to process it responsibly, placing increasing pressure on ecosystems, natural resources, public health, and the well-being of future generations.

One of the most significant shifts required today is a change in how society perceives waste. Rather than being viewed as a material to be discarded, waste must be recognised as a valuable resource that can contribute to both economic growth and environmental protection when managed through the right technologies and systems. This mindset forms the foundation of the circular economy model that countries across the world are increasingly adopting to reduce landfill dependence, recover valuable materials, and create more sustainable industrial ecosystems.

India has made meaningful progress in strengthening awareness around sustainability, recycling, and environmental responsibility over the past decade. Significant efforts are being made to formalise the recycling sector through improved infrastructure, technology adoption, policy implementation, and broader stakeholder participation. These developments are creating a stronger foundation for responsible waste management and resource recovery across the country.

However, achieving long-term environmental impact requires collaboration from all stakeholders. Industries, policymakers, technology providers, and communities must work together with greater accountability to strengthen recycling ecosystems, encourage responsible waste management practices, and create sustainable outcomes through consistent execution rather than temporary interventions.

As someone closely associated with the recycling industry, I firmly believe that technology will play a decisive role in addressing future environmental challenges. Advanced recycling systems have the potential to recover valuable resources, reduce pollution, minimise landfill burdens, and conserve energy, creating a more sustainable future for generations to come. This belief is deeply reflected in Fornnax’s motto, “Committed to Create a Green Future,” which embodies our commitment to building long-term environmental value through innovation and responsible action.

At the same time, technology alone cannot deliver meaningful change. Real progress requires intent, awareness, participation, and a shared sense of responsibility. Sustainable development can only be achieved when innovation is supported by collective action and a genuine commitment to environmental stewardship.

On this World Environment Day, let us move beyond conversations and take meaningful steps towards creating a cleaner, greener, and more sustainable planet. By embracing innovation, strengthening recycling ecosystems, and acting responsibly today, we can create lasting environmental impact and secure a better future for generations to come.

Dalmia Cement executed a Business Transfer Agreement with Jaiprakash Associates and Adani Infra, to acquire 5.2 MnTPA of cement capacity across Madhya Pradesh and Uttar Pradesh.

Dalmia Cement (Bharat) announced on May 22, 2026 that it had signed a Business Transfer Agreement with Jaiprakash Associates Limited and Adani Infra (India) Limited for the acquisition of cement plants located at Rewa in Madhya Pradesh and Churk, Chunar and Sadwa in Uttar Pradesh. The deal was struck at an enterprise value of ₹2,850 crore and is expected to close within two weeks of execution.

The acquired assets from Jaiprakash Associates include 5.2 MnTPA of cement capacity and 3.3 MnTPA of clinker capacity. The package also covers 99 MW of thermal power capacity and railway sidings at Rewa, Chunar, and a common siding at Churk. This infrastructure gives the acquisition immediate operational utility beyond just production tonnage.

The transaction has a long backstory. Dalmia Cement had originally entered into a framework agreement with Jaiprakash Associates in December 2022, covering the sale of these business assets along with a long-term clinker supply arrangement. However, before the deal could be completed, Jaiprakash Associates was admitted to insolvency proceedings under the Insolvency and Bankruptcy Code. The earlier agreements could not be consummated as a result.

In an official statement, Puneet Dalmia, Managing Director & CEO, Dalmia Bharat, said, “I am very excited about addition of these assets in our portfolio. This serves as a great strategic fit for Dalmia. It helps us move forward in our journey to be a pan India player and provide a strong head start to serve the high potential markets in Central region. I am optimistic that the expansion potential of these assets along with close proximity with Dalmia’s captive mines will help us create a capacity hub for the future”.

Following the approval of Adani Group’s resolution plan for Jaiprakash Associates under the IBC framework, Dalmia approached the new management to revive discussions. The fresh Business Transfer Agreement was executed to settle all pending disputes, legal proceedings, and arbitration matters arising from the original framework agreement with Jaiprakash Associates.

Expanding market reach

Dalmia added, “Our familiarity with these assets under the earlier tolling arrangement gives us a deep understanding of the facilities and helps us establish strong connect with channel partners and vendors. We believe that this will help us in faster ramp up of capacities and quicker inroads into the market. As we look forward, I am very confident that we will be able to leverage the strengths of Dalmia to operate these assets in a manner where we can maximise value creation for all our stakeholders.”

With the addition of these plants, Dalmia Bharat’s total installed cement capacity will rise to 54.7 MnTPA upon consummation. The company has further expansion projects underway at Belgaum, Pune, and Kadapa, which are expected to take overall capacity to 66.7 MnTPA by Q2 to Q3 FY28.

The Central India location of the Jaiprakash Associates plants gives Dalmia Bharat faster access to markets in Madhya Pradesh and Uttar Pradesh than a greenfield build would have allowed. The company also cited debottlenecking and brownfield expansion as near-term opportunities at the acquired sites. Dalmia Bharat said the assets were expected to contribute positively to EBITDA and overall returns, given the pricing environment in the region and the company’s cost structure.
